pe42850RFMW, Ltd. announces design and sales support for two new Peregrine Semiconductor SP5T switches targeting T/R and filter-band switching in Land Mobile Radio (LMR) and Military radio applications where high power handling (17W) is required. Both the PE42850 and PE42851 feature low power consumption of 130 microamperes which helps to extend battery life in mobile applications.

The Peregrine PE42851 covers the frequency range of 100 to 1000 MHz while the PE42850 extends the low end frequency to 30 MHz. Both Peregrine switches feature a low, mid-band insertion loss of 0.25 dB, thereby reducing signal attenuation and resulting in less heat dissipation and improved performance. In addition to SP5T, the new switches can be configured as SP3T devices, giving designers the flexibility to use one switch in multiple locations, for multiple purposes throughout the RF signal chain.

The Peregrine Semiconductor PE42850 and PE42851 RF switches are available in a 32-lead, 5 mm x 5 mm QFN package.
